1. What is Dog Pregnancy Week Calculator?

The Dog Pregnancy Week Calculator estimates the current week of pregnancy based on the mating date and current date. It helps dog owners and breeders track the progression of pregnancy and prepare for whelping.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Current\ Date \) — Today's date or any specified date
• \( Mating\ Date \) — The date when mating occurred
• \( \lfloor \rfloor \) — Floor function (rounds down to nearest integer)

Explanation: The calculator calculates the number of days between the mating date and current date, then divides by 7 and rounds down to get the complete weeks of pregnancy.

3. Importance of Pregnancy Tracking

Details: Accurate pregnancy tracking is essential for proper prenatal care, nutrition planning, and preparing for the whelping process. It helps identify the expected due date and monitor fetal development stages.

4. Using the Calculator

Tips: Enter the exact mating date and the current date (defaults to today). The calculator will display the current week of pregnancy. Normal dog pregnancy lasts approximately 63 days (9 weeks).
